What is Metabolism? 

Metabolism is the complex set of chemical processes that occur in living organisms to maintain life.

It involves the conversion of food into energy & the building of molecules necessary for the growth, repair, & maintenance of tissues & organs.

Metabolism can be divided into two main categories: catabolism & anabolism.

Catabolism is the breakdown of larger molecules into smaller ones, typically releasing energy in the process.

 Anabolism is the synthesis of larger molecules from smaller ones, often requiring energy. 

The metabolic process begins with the digestion of food, which breaks down carbohydrates, proteins, & fats into their respective components: glucose, amino acids, & fatty acids. 

These components then enter the bloodstream & are transported to the body's cells, where they further processed through a series of complex biochemical reactions that involve enzymes & hormones.

The rate at which an individual's body burns calories, or their metabolic rate, is influenced by a variety of factors, including age, sex, body composition, & physical activity level.

People with a higher percentage of muscle mass generally have a higher metabolic rate, while those with more body fat typically have a lower metabolic rate.
